Notes

Why is iodine required?

Corals might require iodine as a de-toxifier, as a protection against uv-radiation and as a natural defense against many parasites.
Iodine is present in NSW (Natural Sea Water) in a very low concentration (0.06 mg/L or 0.06 ppm).
Iodine occurs in NSW as different species. These include iodide, iodate, molecular iodine and hypoiodite.
Generally when we say iodine we mean one or more iodine species without a clear distinction being made. NSW contains predominantly iodate and to a lesser extent iodide. There is however a misconception among many hobbyists that iodide predominates in NSW. Research by Salifert and universities has proved this to be untrue.
